Stage Safety

At live events, where there are spectators and actors, situated beneath a great weight of hanging audio, video and lighting apparatus, the people below have to be protected from falling equipment by the implementation of strict and rigorous safety and overload prevention precautions.

Each time there are more than two hoists on a truss or more than three hoists in a structure, it becomes statically indeterminate, resulting in an unpredictable load distribution. In most cases this will cause a load imbalance, in which some of the hoists may reach overload while others carry only a small part of the load

Unpredictable load distribution is not just a phenomenon in physics. It is of major importance to our day to day entertainment rigging reality.

The solution to protect human lives, expensive equipment and your venues’ infrastructure from rigging hardware failure is continuous load monitoring from the moment the equipment is lifted until the time comes to bring it back down.

Ron StageMaster is the ultimate solution for unpredictable load distribution and the consequential dangerous overload.

Ron StageMaster is an advanced wireless and wired load monitoring system, chosen by the most professional riggers, world tours and venues worldwide:

  • All Eilon Engineering load cells are Fatigue Rated as required by ASME BTH-1       

  • Bluetooth compatibility with iPhones / iPads

  • Combination of wireless and wired load cells in one system  

  • Continuous Load Monitoring 24/7/365

  • Extremely long  Battery Life up to 8,000 hours - The amazing extended battery life eliminates the need for sleep or standby mode or even worse: powering down of the system, which are all unsafe.   

  • Accuracy of 0.1% of full scale

  • 200 Load Cells per receiver

  • A real time load map allows riggers to easily notice a developing overload and take   

            immediate preventative action

  • Set point option for E-stop (connects to any controller)   

  • Downloadable reports of months of continuous measurements.

  • Safety Factor 5:1, 10:1 and higher. Capacities up to 300t

  • Extreme Range up to several km/miles. (optional)

  • SMS alert on overload / underload occurrence

  • Chosen by NASA, Cirque du Soleil, Boeing, Tait, PRG, Walt Disney and many others

  • 40 years of proven Wireless Technology
